SEAL-PADLOCK.

Speccaton of Letters Patent.

Patented June 11, 1907.

Application iiled January 14,` 1907. Serial No. 352,166

To all Uh/0m, it' may concern.-

Be it known that I, FREDERIC ABRAMs, a citizen of the United States, residing at Ennis, in the county of Ellis and State of T eXas, have invented certain new and useful Improvements in Seal-Padlocks, and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention relates to seal pad-locks.

The object of the invention is to render it absolutely impossible to gain access to the interior of the lock for the purpose of releasing the tumbler' from the shackle without breaking and destroying the seal, and to preclude the possibility of applying a spurious seal to the lock when the shackle is in locked position.

lVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a lock and seal, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in 'which like characters of reference indicate corresponding parts,-Figure 1 is a view in front elevation, and with parts broken out of a lock and seal constructed in accordance with the resent invention 5 Fig. 2 is a view in rear e evation, with a portion of the casing broken away Fig. 3 is a view in front elevation with the cover of the casing removed, with certain parts broken away to exhibit more particularly the construction of the casing 3 Fig. 4 is a view in end elevation looking in the direction of the arrow on Fig. 1; Fig. 5 is a horizontal sectional view taken on the line 5 5, Fig. 3, Fig. 6 is a vertical transverse sectional view taken on the line 6 6, Fig. 3.

This seal lock is especially adapted for use on car doors, and will be described in reference thereto. The body of the lock comprises, as usual, a casing 1, and a cover or lid 2, which is held assembled with the casing in any preferred manner as by the employment of teats or studs 3 that engage suitable orifices 4 in the casing and cover, and are upset and if desired brazed to insure a more stable union between the parts. The cover is provided with an opening 5, back of which is arranged a seal 6 of glass or other suitable frangible material, the lettering and figuring on the seal being blown therein, to render it impossible to duplicate a seal except by the factory, and this is a safe-guard against imitation.

Pivotally mounted on a stud 8 within the casing is an L-shaped or bell crank tumbler 7. This stud 8 is preferably integral with the casing and a pin 9 seated in a-recess 10 in the tumbler to avoid any interference with the proper operation of the seal holds said tumbler on the stud. The tumbler is provided, as usual, with ahook 11 that isadapted to interlock with a hook 12 of the shackle 13, the shackle being guided in movement to and from the casing by a shank 14 slidable in one end of the casing, and is held against disconnection therefrom by a stud 16 that engages with a flange 17, as clearly shown in Fig. 3. The tumbler is held normally in engagement with the nose of the shackle by a coiled spring 18 that is housed in a longitudinally disposed cored-out lug 19 arranged near the top of the casing. This arrangement insures the proper operation of the spring, and also prevents its accidental separation or disconnection in use.

The long or horizontal arm 20 of the tumbler is engaged by a combined tumbler-releasing and seal-breaking member comprising a threaded bolt 21 that projects through a threaded lug 22 on the back of the casing, an approximately conical head 23 rigidly attached to or integral with the bolt and constituting the seal-breaking and tumbler releasing means, and a milled or knurled knob 24 by which the bolt is turned. The head 23 operates not only to depress the tumbler and move it out of engagement with the shackle, but also prevents detachment of the bolt from the casing, as it will be seen when it is moved rearward it will contact with the inner wall of the casing checked.

The head 23 is not a true cone throughout its entire length, but is provided with a reduced terminal 25 that is adapted to contact with and break the seal 6, when the Abolt is turned in the proper direction, in advance of the release of the tumbler from the shackle,

and thus have its motion4 IOO thus to preclude the-possibility of detaching the lock without first destroying the seal. The shackle is attached to the car by one end of a chain 26, the other end of which is secured to a clip 27 pivoted to the shackle.

In order to permit insertion of the seal when the shackle is unlocked, one end of the casing is provided with a seal-receiving opening 28 which is of a width at least equal to that of the seal, and as clearly shown in Fig.

IIC

l, is normally closed by the shank 14, whereby tion, and number can be seen at a glance,

Which will effect a saving of time in taking seals. It makes it impossible for the hasp on the car door to jar oil the shackle and allow the car door to slide back and break seals. It precludes the possibility of opening the lock without first breaking the seal. When broken it will be discernible at a glance and at a considerable distance, which will not only be of advantage to the train men in protecting their trains against thieves, but will enable the officials to place the responsibility of broken seals on the party at fault. The lock being attached to the car is thereby made a part of the equipment, and leaves only the seal or glass to be destroyed, thus making it very economical. The lock and seal is so constructed that it cannot be applied wrong, neither can it be attached upside down or backward, but always hangs face out, and therefore does not have to be twisted and turned in order to observe the seal.

I-Iaving thus described my invention, what I claim as new and desire to secure by Letters-Patent is,-

1. A lock casing provided with a shackle, a tumbler disposed in said casing, a frangible seal, and a conical tumbler-releasing and sealbreaking member carried by the casing and operative transversely thereof at right angles to the seal.

2. A lock casing, ya tumbler therein', a rangible seal, and a screw-threaded bolt having a conical tumbler-releasing and sealbreaking head.

3. A lock casing, a tumbler therein, a Jrangible seal, and a screw-threaded bolt having a tumbler-releasing and seal-breaking head of greater cross diameter than the bolt to prevent disconnection of the bolt from the casing.

4. A lock casing, a shackle, a shackle locking tumbler within the casing, and a threaded bolt having a conical head to release the tumbler from engagement with the shackle.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FREDERIC ABRAMS.
